Abstract

See full text

A desktop illumination device includes a light source; and a light guide including a light guide plate. The light guide plate has a light incident surface and first and second main surfaces. An angle at which an intensity becomes maximum in a light distribution of light emitted from the first main surface is in a range of −90° or more to less than 0°, in a case where an axis passing through a center of the first main surface and perpendicular to an installation surface is defined as a vertical axis, and in a plane including the vertical axis and perpendicular to the installation surface, a direction parallel to the installation surface is defined as vertical 0°, an upward angle with respect to the vertical 0° is defined as a positive angle, and a downward angle with respect to the vertical 0° is defined as a negative angle.
